As shown in FIGS. 20 to 23, a structure and a method for installing the ice-making housing 110 on the inner case side surface 15 a of the refrigerating compartment 10 a will be described.

An ice-making housing mounting portion 150 for installing the ice-making housing 110 is formed in the inner case side surface 15 a of the refrigerating compartment 10 a. The ice-making housing mounting portion 150 may be formed at a position corresponding to the ice-making housing 110. The ice-making housing mounting portion 150 may include a first fixing hole 151 and a second fixing hole 152. Each of the first fixing hole 151 and the second fixing hole 152 may formed as one or a plurality of holes. In the embodiment of the present disclosure, a pair of first fixing holes 151 and a pair of second fixing holes 152 are disposed at a predetermined distance from each other, but the spirit of the present disclosure is not limited thereto. For example, the first fixing holes and the second fixing holes may be a plurality of holes.

The first fixing hole 151 and the second fixing hole 152 may have different sizes. Each of the second fixing holes 152 may be disposed on one side and the other side of the first fixing holes 151, respectively. In the embodiment of the present disclosure, the second fixing holes 152 are disposed at outer sides of the first fixing holes 151, but the spirit of the present disclosure is not limited thereto.

A plurality of fixing protrusions 171 and 172 may be disposed on the bottom panel 110 c of the ice-making housing 110. A first fixing protrusion 171 and a second fixing protrusion 172 respectively corresponding to the first fixing hole 151 and the second fixing hole 152 are formed on the first coupling surface 110 e of the bottom panel 110 c.

The first fixing protrusion 171 corresponds to the first fixing hole 151, and the second fixing protrusion 172 corresponds to the second fixing hole 152.

Here, the second fixing protrusion 172 includes a locking portion 172 a formed to protrude in a rearward direction of the ice-making housing 110.

The first fixing protrusion 171 may include a first fixing portion 171 a extending from the first coupling surface 110 e and a second fixing portion 171 b formed at an end of the first fixing portion 171 a. The first fixing protrusion 171 may be formed in a substantially T shape. The first fixing portion 171 a may have a first width t1, and the second fixing portion 171 b may have a second width t2. The second fixing portion 171 b may be larger than the first fixing portion 171 a. The first width t1 of the first fixing portion 171 a is smaller than the second width t2 of the second fixing portion 171 b.

Further, a fixer 160 configured to fix the first fixing protrusion 171 may be coupled to the first fixing portion 171 a of the first fixing protrusion 171. The fixer 160 includes a fixer groove 161 having a shape corresponding to the first fixing portion 171 a. The fixer groove 161 may have a size corresponding to the first width t1.

Accordingly, the ice-making housing 110 is positioned to correspond to the ice-making housing mounting portion 150 of the inner case side surface 15 a of the refrigerating compartment 10 a, and the first fixing protrusion 171 and the second fixing protrusion 172 of the first coupling surface 110 e of the ice-making housing 110 are respectively inserted into the first fixing hole 151 and the second fixing hole 152.

Then, the ice-making housing 110 is moved to the inner case rear surface 15 b side.

The second fixing protrusion 172 is inserted and moved into the second fixing hole 152 and the locking portion 172 a is locked in the second fixing hole 152.

Further, the first fixing hole 151 is formed long in a longitudinal direction so that the first fixing protrusion 171 of the ice-making housing 110 is inserted thereinto and moved backward.

When the second fixing protrusion 172 is locked in the second fixing hole 152, the first fixing portion 171 a of the first fixing protrusion 171 is fixed by the fixer groove 161 of the fixer 160. The fixing of the first fixing protrusion 171 and the fixer 160 may be implemented outside the inner case side surface 15 a of the refrigerating compartment 10 a. When the first fixing protrusion 171 is fixed by the fixer 160, the ice-making housing 110 may be firmly fixed by foaming between the outer case 14 and the inner case 15 of the refrigerating compartment 10 a.

According to embodiments of the present disclosure, an insulating effect can be improved by the ice-making compartment with an improved structure.

Further, the cool air inflow chamber capable of maintaining a low temperature is formed inside the door, and thus a low temperature product can be stored.

Further, the gasket mounted onto the ice bucket cover is formed inside the door to reduce icing due to leakage of cool air of the ice-making compartment caused by an error in mounting the ice bucket, and the ice bucket installed in the ice-making compartment does not have a separate seal for preventing cool air leakage so that the structure can be simplified. Moreover, there is no need for a separate locking device or the like, and thus detachment can be facilitated.

Further, it is possible to improve an assembling property of the ice-making housing to improve the airtightness of the ice-making compartment, simplify a structure and improve durability.
